Quantification of (A) average mitochondrial area, (B) altered mitochondria, and (C) multivesicular bodies in alveolar type II cells as determined by using the National Institutes of Health ImageJ software. Altered mitochondria were determined as percentage of total number of mitochondria; multivesicular bodies were determined as total number in a single cell. Data are expressed as mean ± SEM. *P < 0.05 versus age-matched control mice; ^#P < 0.05 versus vehicle-treated group of the same age; ^‡P < 0.05 versus young group.
